Overview Effect of Biodiesel Storage on Properties and Characteristics

Abstract

Abstract. Biofuels based on vegetable oils offer the advantage being a sustainable and environmentally attractive alternative to conventional petroleum based fuel. The key issue in using vegetable oil-based fuels is oxidation stability, stoichiometric point, bio-fuel composition, antioxidants on the degradation and much oxygen with comparing to diesel gas oil. This provides a critical review of current understanding of main factor in storage method which affecting the biodiesel properties and characteristics. In the quest for fulfill the industry specifications standard; the fuel should be stored i n a clean, dry and dark environment. Water and sediment contamination are basically housekeeping issues for biodiesel. Degradation by oxidation yields products that may compromise fuel properties, impair fuel quality and engine performance. The effect of storage method on the fuel properties and burning process in biodiesel fuel combustion will strongly affects the exhaust emissions. IntroductionBurning fossil fuels such as coal, diesel and gas produces greenhouse gases give impacts on the environment. A range of greenhouse gases were produced when fossil fuels are burned, these gases include carbon dioxide, water vapour, methane and nitrous oxides. These gases trap the sun's heat in the atmosphere, it concentrate and increase the heat of the sun where it works quite similar to the lens in a magnifying glass. This is called the greenhouse effect.Studies have found that first-generation biofuels produced from current feedstock's using the most efficient systems and carbon releases results in emission reductions in the range of 20-60 per cent relative to fossil fuels. Generally, biofuels offer many priorities, including sustainability, reduction of greenhouse gas emissions, regional development, social structure and agriculture and securi-

Effects of Storage Characteristics on Flash Point and Water Content of Biodiesel derived from Crude Palm Oil, Jatropha, and Waste Cooking Oil

“…Furthermore, researcher monitored the production of acids, peroxides, and aldehydes, as well as increase in viscosity induction storage time over a period of 90 days [5][6][7][8][9]. It found that the stability of biodiesel for 180 days of storage showed that exposure to metals also increased the rate of degradation and exposure to higher temperatures in pro-oxidizing conditions accelerated loss of stability [10][11][12][13][14][15]. Previous researcher also found that sunlight give higher increasing rate of acid value and antioxidant gave a significant increase in kinematic viscosity which reflects from different storage condition [5][6].…”

The Storage Effect on Fuel Properties and Emission for Variety Biodiesel Blends

“…The high level of water content can causes problems to the engine such as fuel filter plugging, corrosion to the engine compartment, fuel degradation and also microbial growth [8]. The problems arises can affect the total performance of the engine itself [8][9]. For an ideal combustion reaction in the diesel engine, the combustion of fuel in oxygen will produces water and carbon dioxide (CO 2 ), however the ideal reaction is unlikely to happen in real situation.…”

“…However high blending ratio of biodiesel cannot be used directly to the diesel engine as it contains high level of water content. The high level of water content can causes problems to the engine such as fuel filter plugging, corrosion to the engine compartment, fuel degradation and also microbial growth [8]. The problems arises can affect the total performance of the engine itself [8][9].…”

“…According to , biodiesel that stored in long storage duration can affect the oxidation stability, fuel degradation and microbial growth [8]. Moreover, if the fuel is exposed to the air while storing, the degradation of fuel properties will increase rapidly.…”
